Analysis of Supercritical Flow In Suddenly Expanding Channel

Sumit Gandhi
Jaypee University of Engineering & Technology, Guna India

ABSTRACT

The experimental analysis is carried out to study the variation of flow characteristics namely sequent depth ratio (Y2 / Y1), Relative height of jump (hj / Y1), relative energy loss (EL / E1), Efficiency (E2 / E1), Relative length of jump (Lj / Y1) and relative length of roller (Lr / Y1) of the hydraulic jump for suddenly expanding channel for different B1 / B2 (expansion) ratio. Dimension of baffle blocks and end sill are also considered as the third variable. Explanations of the variation of these characteristics with approach Froude number is presented based on experiments. Empirical models are presented using Buckinham's π-theorem; these models are tested, validated and compared with other authors result. Modifications in energy dissipation as a result of application of appurtenances are obtained showing usefulness to its dimensions.
